Dry and Mild September 2018

Temperatures were near normal, with a number of warm nights. There was just one very cool day that reached only 14.8°. The first 30° day of spring came on the 14th. The early morning dew point on the 17th, minus 10.5°, was the lowest September value, but far from the lowest recorded recently.
There were eight rain days, but the highest reading was only 3.6 mm, on the first day of the month.

Comparing September months

Despite being within an extreme drought, moisture measures this month were not very low; not as low as in September 2017. While the mean temperature was normal, the daily temperature range was low, which is unusual in a drought.
The rainfall total of 12.5 mm (estimated) is at the 18th percentile for September.
I have reported the shortage of rainfall in another post: “Record 15-Month Drought in 2018”.

Climate in September months


Data. A Bureau of Meteorology automatic rain gauge operates in the museum yard. From 17 March 2017, 9 am daily readings are published as Manilla Museum, Station 55312.  These reports use that rainfall data when it is available.  The record was again defective in September 2018. No 9am readings were recorded. I have substituted my non-standard gauge readings for all days.
All other data, including subsoil at 750 mm, are from 3 Monash Street, Manilla.
